It is evening, dark. There is a traffic jam in the Elbtunnel as always. Suddenly, a gunshot. The driver of a white SUV slumps over the steering wheel. The perpetrator escapes unnoticed. A rampager? The beginning of a gang war? All leads lead to nowhere. And then, all of a sudden, an American intelligence agency takes an interest in the case. Chief Inspector Adam Danowski is considered unpredictable despite his recent investigative success. This time, he also follows his own path. It leads to a new housing development amidst vast moor meadows on the outskirts of the city, to abandoned places and dark secret passages.
